Title: Process for fireproofing textile fibres
Inventor: SENEZ CLAUDE JEAN MICHEL
IPC: D06M15/673
Filed: 1963-02-18
Abstract: Aqueous "reactive derivative" being a compound which condenses with -OH or -NH- groups, whose residue after such condensation contains at least 20% N, and "fire-proofing agent," being an aqueous solution of products resulting from the action of NH3 and CH3OH on PnNn- 1Cl2n+3, where n is an integer greater than 1, are used consecutively or in admixture to treat textile fibres.  The "reactive derivative" e.g. hexamethylol melamine, polymerized methylated hexamethylolmelamine, cyanuric chloride, triaziridinylphosphine oxide, and trimethylaziridinylphosphine oxide, reacts with the textile and/or the fireproofing agent, which may be P4N3Cl(OCH3)5(NH2)5, whose preparation is described in Specification 947,634, with or without (PNCl2)n polymers. Specification 865,396 is also referred to.ALSO:Textile fibres are fireproofed by impregnation with a fire-proofing agent being an aqueous solution of products resulting from the action of NH3 and CH3OH on PnNn-1CP2n+3 where n is an integer greater than 1, and with an aqueous "reactive derivative" having a high content of nitrogen, and thereafter heat-treating the fibres at 100 DEG -200 DEG C.  The "reactive derivative" is a compound which condenses with -OH or -NH- groups, whose residue after such condensation contains at least 20% N : e.g. hexamethylolmelamine, polymerized methylated hexamethlolmelamine, cyanuric chloride, triaziridinylphosphine oxide, and trimethylaziridinylphosphine oxide.  The "reactive derivative" and the fire-proofing agent may be applied in the same or in different baths, urea being present.  (PNCl2)n polymers may also be present.

Title: Improvements in or relating to methods of and apparatus for electric spot welding
IPC: B23K11/11
Filed: 1951-03-16
Abstract: 715,686. Welding by pressure. GENERAL ELECTRIC CO., Ltd., and DONELAN, J. A. March 17, 1952 [March 16, 1951], No. 6410/51. Class 83 (4). In electric spot welding two or more superposed pieces of material current is passed between two electrodes in contact with only one surface of one of the pieces to raise the material beneath at least one of the electrodes to welding temperature, the flow of current between the electrodes being solely through the material to be welded. Two welds may be made simultaneously by two rod-like electrodes of the same contact area. A single weld is made by one electrode 10, Fig. 3, about which is disposed an electrode 20 in the form of a fork having a larger contact area. One of the electrodes 10, 20 may be resiliently mounted and may project beyond the other. Each electrode may be mounted to apply pressure to forge the weld or welds. To produce a solid spot or ring-like weld between plates 12, 13, 14, Fig. 4, on an insulating backing 15, concentric electrodes 10, 30 are employed. Electrode 30 is insulated from electrode 10 by a bushing 31 on which it slides under a spring 32. Copper pieces between 0.003 and 0.02 inches thick may be welded to copper foil 0.0005 inches thick secured to a resin-bonded laminated insulating material. A multiplicity of welds may be produced by using groups of electrodes, those in one group being connected parallel together and insulated from those of the other group. Specification 509,548 is referred to.

Title: Improvements in and relating to the starting mechanism of internal combustion engines
IPC: F02N1/02
Filed: 1923-03-08
Abstract: 205,763. Whitham, J. H. March 8, 1923. Turning-gear.-In a starting-device in which an expanding clutch d actuated by a handle p engages a drum b secured to the engine shaft a but allows free forward or reverse rotation of the shaft when the engine starts, the clutch d is expanded and contracted 'by a member f actuated by ratchet-and-pawl mechanism, the pawls j, k being in axial relation with one another. The clutch d consists of two semi-circular members connected by springs and pivoted upon a disc e rotatable on an extension c of the engine shaft. Between the ends of the clutch is the member f rotatable on the disc e and having a head g carrying the pawls j, k, which are held by a spring in engagement with a fixed ratchet m and a ratchet-wheel n on the hub o of the starting- handle p. When starting, the rotation of the handle p and wheel n tilts the pawl and the members g, f , so expanding the clutch d and driving the engine shaft, while the pawl k slips over the ratchet m. If the engine starts normally. the pawls slip idly over both ratchets m, n. If the engine turns backwards, the pawl k is held by the ratchet m and the member f is tilted back into the position shown in Fig. 3, releasing the expanding clutch. The angular movement of the member f is limited by a pin s passing through it and engaging a stop t on the plate e.

Filed: 1926-03-10
Abstract: 249,506. Haefely et Cie, Akt.-Ges., E. March 20, 1925, [Convention date]. Transformers; condensers.-In insulating devices for high-tension elertrical apparatus such as leading-in devices, transformers, and condensers, of the type in which the insulating radium is compressed air, the pressure is concentrated only on the critical points by means of compressed-air containers, and the degree of pressure is arranged so that the striated discharges occurring at certain points shall not be liable to develop into brush discharges. 'As applied to the insulation of a leading-in device, Fig. 1, the leading-in bolt a is surrounded by a compressed air chamber b enclosed by an insulating wall c. The pressure is controlled by a supply pipe e and a pressure gauge i, which may be provided with a warning device to indicate unsafe decrease of pressure, or with means for preventing the switching-in of the device until a predetermined pressure is reached. The supply valve e may be mounted in the earthed flange ring d, or in part at high potential, in which case it should be connected to the air supply by a length of insulating tubing. The air may be kept at constant pressure by supplying it from a reservoir or compressor controlled either manually or automatically in accordance with the gauge readings. The pressure in the insulating chamber may be maintained by inserting liquid or solid vaporizing substances such as carbon dioxide and ether. The pressure may be graded down from the high tension bolt b by providing a series of concentric chambers. Fig. 3 shows the application to a transformer, in which the air chamber b, interposed between the primary and secondary windings, is formed by a hose or tube g of material such as rubber, impregnated fabric balloon material, or leather. Specifications 13677/05 and 13679/05 are referred to.

In a diaphragm structure for the low-pressure stage of a steam turbine, the stator blades are made partially or wholly of porous metal and by means of internal passages in the diaphragm structure are connected to a receiver at a lower pressure than the turbine stage, whereby moisture impinging on or flowing over the porous surface of the blade is drawn off. The blade in Figs. 1 and 2 comprises a tubular portion 1 at the leading edge made of porous sintered metal, and a solid main portion 2, for example, of stainless steel. The portion 2 is cast into an outer ring 3 and into the centre plate 4 of the diaphragm. The tubular portion 1 is brazed into outer and inner hollow rings 5 and 6 and these rings are connected by screws 7 to the outer ring 3 and the centre-plate 4.
